What is speed?

In this tutorial you will learn the basic definition for speed.

Summary

  1. m/s- meters per second, the common unit for speed

Notes

    1. It's always a good idea to understand physics terms with just words
    1. Here's a nice trick: the units of speed (meters divided by seconds) help you remember what the equation for speed is (distance divided by time)
    1. When you have constant speed, the d= s•t equation becomes really important
    1. v with an arrow- the velocity vector
    2. length is always positive, and so speed is always a positive number
    1. The speed that an object has at some instant is the instantaneous speed
    1. The total distance divided by the total time to cover that distance is the average speed
